Tuya Wi-Fi LED Dispay Temperature & Humidity Sensor Product parameters: APP name: Tuya Smart or Smart Life Work with Amazon Alexa/Google Assistance Input: DC5V/1A Wi-Fi Standard: IEEE 802.11 b/g/n, 2.4GHz Support all Tuya smart product Linkage control Temperature Measure Range: 0 ~ 60 Humidity Measure Range: 0% RH~99% RH Selectable temperature format C / F Temperature/Humidity high/low/release status will synchronization to app Display time/temperature/humidity/WIFI Size: 85*85*18mm Product Features: 1. Wifi+Bluetooth Dual Mode Connect to the network faster. The connection network speed is 2 times faster than only Wifi. (Bluetooth is only used for network signal connection, Bluetooth cannot be used alone. WIFI+Bluetooth is more stable) 2. High temperature/humidity and low temperature/humitity alarm Once the temperature/humidity exceeds the set value, the phone will prompt an alarm. 3. Real-time monitoring and recording. The sensor uses USB power supply. Compared with the battery version, the sensor will monitor the temperature and humidity in real time. The sensor will report when the temperature and humidity changes very little. You can view the changes in the value on the APP or display screen. Record the temperature and humidity changes on the APP, and use the graphics to show you. 4. Temperature /Humidity calibration You can set the temperature/humidity value that you want. First choose 0 "or 0%"and confirm in app first, then choose other number and confirm. (Default is 0) 5. Large LED screen display The sensor uses LED as the display of temperature and humidity, and the display of time is added on the screen. Time is automatically calibrated. 6. BlackLight Supported Backlight can be turned on/off by app or can be done timing truned on/off by app. 7. Intelligent Linkage The temperature and humidity sensor can be linked with other smart devices in the home to improve the indoor heating and cooling, and make your home more comfortable. When the ambient environment change, you can do intelligent linkage. For example, the air conditioner will be on automatically when the room temperature surpass 35. And the humidifier will spray when the humidity is lower than 20% RH. (Note that this function needs to be used with a universal infrared remote control or WIFI switch). 8. Temperature Unit Selection in APP The sensor is designed with a temperature conversion function between Celsius and Fahrenheit. You can select the unit to be displayed according to your needs. You can choose or as the temperature unit through app. 9. Third-party voice support This sensor supports Amazon Alexa and Google Home Assistant. You can hear the current temperature and humidity by voice. 10. Share devices You can share your added devices with your family members, so they can also monitor the ambient environment.
